Telemetering alarming device for dispatching automation system

Abstract

The invention provides a telemetering alarming device for a dispatching automation system. The telemetering alarming device comprises an RTU (Remote Terminal Unit) for telemetering, wherein the RTU is connected with a main distribution cabinet through an optical fiber, the main distribution cabinet is connected with a communication controller, the communication controller is connected with a front server used for analyzing a protocol message and carrying out information sequencing and arranging, the main distribution cabinet is also connected with the front server through a communication testing cabinet and an MODEM (modulator-demodulator) analog-to-digital conversion device, the front server is connected with a switchboard, and the switchboard is respectively connected with a data server, a PAS (Provox Application Server) and a Web server. According to the telemetering alarming device, alarm signals can be rapidly distinguished, so that a power grid manger can conveniently works for monitoring, the load of the manager is reduced, and the normal operation of the power grid is ensured.

Description

technical field [0001] The invention relates to a telemetering and alarming device for a dispatching automation system. Background technique [0002] In the prior art, it is known that the amount of telemetry information processed by the dispatching automation system is huge, and the current telemetry over-limit alarm does not distinguish between primary and secondary signals, and does not divide them in detail. With the continuous increase of power grid plants and stations, telemetry information has brought tremendous pressure on the monitoring of power grid management personnel, especially when abnormalities or accidents occur in the power grid. The real-time information of equipment such as lines, plants and stations, and users increases the burden on grid managers to judge and deal with problems, and brings major hidden dangers to ensure the safe, reliable, and high-quality operation of the grid. This is the weak point that existing technology exists. Contents of the...
